GapApp Fractions is an app designed to help learn the math skills needed to add, subtract, multiply, divide, and compare fractions. This app starts out with adding positive numbers, and builds up to multiplication, division, addition and subtraction of fractions. The final module covers how to compare two fractions.
Topics covered include:
-adding positive integers
-subtracting one positive integer from another
-adding integers
-subtracting integers
-multiplying positive integers (basic times table)
-multiplying integers
-factoring positive integers
-reducing fractions
-finding the GCD of two positive integers
-finding the LCM of two positive integers
-multiplying fractions
-dividing fractions
-adding fractions

There are two modes for this app: the "Gap Check" mode and "Free Play" mode. A module must be completed in Gap Check mode before being accessible in Free Play mode. To unlock a module, the user must correctly answer 5 questions in a row. If the user answers a question incorrectly, the status level is reset to 0 and the user starts the module over. Once a module is unlocked, the user can practice those types of problems in Free Play.
This app generates practice problems for the user to solve. Solving 5 problems in a row in a module "unlocks" the module for further practice (in freeplay mode). Working through the Gap Check mode provides a reference level for accuracy and time. As the user unlocks levels and practices solving the problems in Free Play mode, improvement against this reference level can be monitored.
This app makes use of the Game Center. Achievements for speed and accuracy can be unlocked, the Leaderboard can be used to compare scores, and users can challenge others to beat their times or unlock achievements.
